5. Setup

5.1 Charging the Device

Before first use, fully charge the device using the provided USB-C cable and a compatible power adapter. The digital display will indicate the charging status and battery level.

5.2 Attaching Nozzles

Select the appropriate nozzle for your task. Align the nozzle with the device's outlet and gently push and twist to secure it. For the DA970 model, to use the suction function, attach the vacuum attachment by rotating it onto the main unit until it clicks into place. Ensure the dust collection cup is securely attached to the vacuum attachment.

6. Operating Instructions

6.1 Power On/Off

• To Power On: Press and hold the Power button until the display illuminates.
• To Power Off: Press and hold the Power button again until the display turns off.

6.2 Adjusting Fan Speed

After powering on, click the Fan Speed button to cycle through the available modes: P0 (low), P1 (medium), and P2 (high). The current mode will be displayed on the screen.

6.3 Activating the LED Light

Once the device is powered on, double-click the Power button to activate or deactivate the integrated LED light.

6.4 Using the Cooling Function

Direct the airflow towards the component requiring cooling. The powerful fan rapidly dissipates heat, ideal for cooling down ICs or other hot parts during soldering or desoldering processes.

6.5 Using the Cleaning (Blowing) Function

Use the appropriate nozzle to blow away dust, debris, or liquid residues from circuit boards, keyboards, or other delicate electronics. Start with a lower speed and increase as needed.

6.6 Using the Suction Function (DA970 Cuul Fan Vac Pro only)

Attach the vacuum attachment and ensure the dust collection cup is in place. Power on the device and select the desired speed. Use the vacuum to pick up small screws, solder balls, or dust from work surfaces. The DA970 model boasts a powerful 130,000 r/min motor for effective suction.

7. Maintenance

7.1 Cleaning the Device

• Wipe the exterior of the device with a soft, dry cloth.
• For the DA970, regularly empty the dust collection cup and clean the filter to maintain optimal suction performance.
• Ensure no liquids enter the device's internal components.

7.2 Storage

Store the device in a cool, dry place away from direct sunlight and extreme temperatures. Keep it in its original packaging or a protective case when not in use to prevent damage.

8. Troubleshooting

• Device not turning on: Ensure the device is fully charged. Connect it to a power source and try again.
• Weak airflow/suction: Check if the nozzle or air inlet/outlet is blocked. For DA970, ensure the dust collection cup is not full and the filter is clean.
• LED light not working: Double-check that the device is powered on and then double-click the power button to toggle the light.
• If problems persist, contact customer support.

10. User Tips

• Choose the Right Nozzle: Always select the most appropriate nozzle for the task. Narrow nozzles provide concentrated airflow for precise cleaning or cooling, while wider nozzles are better for general dust removal.
• Optimal Cooling: For rapid cooling of small components, use the highest fan speed (P2) and direct the airflow precisely.
• Effective Suction (DA970): When using the suction feature, ensure the vacuum attachment is firmly connected and the dust cup is not overfilled for maximum efficiency.
